About Chainlink
Chainlink is the industry-standard oracle platform bringing the capital markets onchain and powering the majority of decentralized finance (DeFi). The Chainlink stack provides the essential data, interoperability, compliance, and privacy standards needed to power advanced blockchain use cases for institutional tokenized assets, lending, payments, stablecoins, and more. Since inventing decentralized oracle networks, Chainlink has enabled tens of trillions in transaction value and now secures the vast majority of DeFi.
Many of the world’s largest financial services institutions have also adopted Chainlink’s standards and infrastructure, including Swift, Euroclear, Mastercard, Fidelity International, UBS, S&P Dow Jones Indices, FTSE Russell, WisdomTree, ANZ, and top protocols such as Aave, Lido, GMX and many others. Chainlink leverages a novel fee model where offchain and onchain revenue from enterprise adoption is converted to LINK tokens and stored in a strategic Chainlink Reserve. Learn more at chain.link.
About The Role
The CCIP Protocol team is hiring a Software Engineer to design and maintain the services that coordinate fast, fault-tolerant cross-chain transactions under adversarial conditions. This role strengthens the reliability, security, and operational resilience of the core CCIP protocol while helping accelerate protocol performance and long-term ecosystem growth.
Your Impact
- Build and evolve the backend services that power secure, reliable cross-chain message execution across blockchain ecosystems.
- Improve protocol reliability for EVM chains by delivering resilient systems designed with security as a primary consideration.
- Reduce cross-chain transaction latency through optimizations to RPC usage and protocol performance.
- Develop internal tooling that enables faster diagnosis and resolution of production issues during incident response.
- Contribute to protocol security initiatives that strengthen the resilience of CCIP under adversarial conditions.
- Participate in technical design discussions that improve the architecture and long-term scalability of the protocol.
Requirements
- Demonstrated backend engineering experience using Go, Rust, or TypeScript.
- Experience delivering software within crypto projects or remote-first engineering organizations.
- Proven ability to design distributed systems with security and reliability as foundational engineering principles.
- Built or maintained backend systems that operate in production with a focus on resiliency and operational excellence.
- Experience collaborating in engineering design discussions and contributing to technical decision-making.
Preferred Requirements
- Demonstrated knowledge of DeFi protocols and the broader decentralized application ecosystem.
- Experience deploying or operating services using cloud infrastructure and tooling such as containerized workloads and public cloud platforms.
- Hands-on experience using blockchain bridges or interoperability protocols.
- Understanding of bridge-specific security risks and common attack vectors.
- Familiarity with non-EVM ecosystems such as Solana, Aptos, Canton, or similar blockchain platforms.
